Short answer: the Soundcore Motion 300. It ranks #2 of 136 medium speakers by sound quality at $79.99; the Bose Soundlink Flex ranks #34 and costs $84.99, so there is little reason to consider the other one.
What the Soundcore Motion 300 offers: Pretty deep bass for the small size. Pocket size in a big pocket. Can be used in stereo facing you, or omnidirectional lying down. Ability to have a custom EQ for each orientation, standing, lying flat, hanging. Try the Uboom L EQs from Oluv for a more neutral sound. Watch for: Without the above EQ or turning the top 2 treble EQ bars to max, this speaker is very rolled off in the treble and will rank around #50 in the rankings. Bassup mode is worse than Signature. Not quite as detailed or neutral as higher ranked speakers. Slight bass distortion when turned up.
What the Bose Soundlink Flex offers: IP67 rated; rugged enough to survive drops from several feet and floats. Around 12 hours of battery at moderate volume. Watch for: Not stereo. Warm sounding with overly boosted bass which drowns out midrange detail
Buy the Soundcore Motion 300. It ranks higher for sound quality than the Bose Soundlink Flex and costs less, which settles it without a real tradeoff to make.
